The supernova rate per unit mass
F. Mannucci, M. Della Valle, N. Panagia +5
We compute the rate of supernovae (SNe) of different types along the Hubble sequence normalized to the near-infrared luminosity and to the stellar mass of the parent galaxies. This…
Direct evidence of the receding `torus' around central nuclei of powerful radio sources
T. G. Arshakian
The presence of obscuring material (or a dusty `torus') in active galactic nuclei (AGN) is central to the unification model for AGN. Two models, the multi-population model for radi…
Extended Tidal Structure In Two Lyman Alpha-Emitting Starburst Galaxies
John M. Cannon, Evan D. Skillman, Daniel Kunth +4
We present new VLA C-configuration HI imaging of the Lyman Alpha-emitting starburst galaxies Tol 1924-416 and IRAS 08339+6517. The effective resolution probes neutral gas structure…
Cool carbon stars in the halo: a new survey based on 2MASS
N. Mauron, M. Azzopardi, K. Gigoyan +1
We present the first results of a new survey for finding cool N-type carbon (C) stars in the halo of the Galaxy. Candidates were first selected in the 2MASS Second Incremental Rele…
